Simulation results for the spread of the infection in a population at time-step t for different parameters as mentioned in “Simulation and Analysis” for a $0\le d\le 1$ and b $0\le d\le 3$. The colors of the subpopulations are same as shown in Fig. 1. All the transition probabilities are same as mentioned in “Promptness in Implementing Lockdown”
